What does FYI mean?

FYI is an abbreviation of “for your information.” This phrase informs the addressee that the message that follows is simply to provide information and requires no action on their part. It is usually capitalized but can be written in lowercase in informal contexts.

Unlike many internet initialisms, “for your information” is not modern. It dates back to the first half of the 20th century when company workers would send memoranda (memos) to their colleagues. This might have been common practice within press agencies to show that the message was intended for the recipient and not for publication.

How to use FYI in email

While most abbreviations are informal or even slang, FYI abbreviation isn’t. It is a commonplace to use this abbreviation in professional emails. It is ideal as a subject line in a work email to inform the recipient you provide information and do not need them to act or respond. You can also use it in a memo or email to give additional details.

FYI examples in speech
